LAKE GEORGE, Colo. (CBS4) – A wildfire burning about three miles south of Lake George in the Pike National Forest has now burned nearly 1,000 acres in Park County.

The Eleven Mile Canyon Recreation Area and about 150 homes and cabins were evacuated. A Boy Scout camp also had to be evacuated.

The fire was first reported at two to four acres at 1 p.m. Sunday but quickly grew because of the hot, windy weather. About 200 firefighters were battling the blaze. As of 4 p.m. Monday the fire was listed at 970 acres and zero percent contained.

The cause of the fire is still under investigation. There were reports that the fire may have been started by people shooting a gun at a fuel tank, but that has not been confirmed. Investigators on Monday said it could have been caused by lightning, but they were just speculating.

The blaze is not far from where the Hayman Fire originated 10 years ago. That fire is the largest in Colorado history, burning 138,000 acres.
